So, fully extend the upper blades straight out, making sure that the blades don't droop on one side or the other. Hopefully, by now the flybar looks very balanced.

However, if you're talking about having the flybar taken off the helicopter and while it is not linked to anything and it's off balance, then we have an issue.
Thanks, I will check it out tonight when I get home from work.

THE SPRING LOADED THROTTLE
I wish you could just move the throttle to a position and park it like a normal RC throttle. The spring loading is annoying to control. Anybody done a simple mod of eliminating the spring?
LOL ... if you'd have read all 736 pages of this post you'd know all that. J/K

If you get into miro helis, you should try a V911 next. 4-ch is another world.

I checked it out, it is fine.

I have come across two different types of heads. In one version, the screws line up with the pivot pins for the blades, and the hole in the bottom is smaller. In the other version, the screws line up with the flybar and the hole in the bottom is larger and accommodates the sleeve between the upper and lower blades. However, between the two versions, the distance between the flybar and the blades is the same, allowing me to use the same connect buckle.

Without the measurements, I'd say that my rotor head matches the one you bought (the one on the right). Interestingly it has that little "ball" on top, too. So, there stand a chance that your "original" might not be genuine. But I can't call it just yet.

Here's what I would suggest you try: Install the new one, but use only ONE connect buckle instead of TWO. The angle of the flybar and the blades would be slightly off. But fly it, hover it, and see if it doesn't fly okay.
I just wanted to thank Heli Pad for his contributions to this discussion, he helped me figure out the problem with my s107 which recently went down for repair.
I had ordered a main shaft for the upper rotor assy due to pins shearing off (only after dozens of crashes, these little helis are fun and tuff.) Anyway with the new upper assy installed, the heli did not fly right. Found out it was due to the flybar on the replacement assy being at a diff angle than the one on the original assy. if i connect both buckles the flybar is way too tight and I get forward flight into the ground. If I connect one buckle I can fly but its a bit erratic. So now I am trying to get a new part from the amazon seller... will see how that goes.
Anyways, thanks again Heli Pad.

I got mine from Battery Superstore on Amazon for just under $20 with free shipping available. I received it last week and it is also a genuine 107g.

Truly amazing how cheap these "toys" are!


EDIT...what a minute. I put a flight in yesterday using the controller from #1. I swapped the batteries over to the new controller and had some odd problems. First, it wouldn't bind up. I tried both bands multiple times. Finally and suddenly, it bound. Then it powered up - even though I wasn't touching the controller. I jiggled the accelerator and it calmed down but that happened several times. Almost like it would just idle.

Oh well...I have another controller to use. just odd that it would act like this.

These IR controlled toys don't really "bind" in the traditional sense as in using a RF controller. If you're having issues controlling the helicopter and then all of a sudden it begins to work, or "bound" as you put it, chances are some initial conditions haven't been met. Two things you need to do for these genuine S107 to work:

1) Throttle stick must be at zero in the beginning.
2) Gyro must stabilize (indicated by the LED on PCB going solid).

So when you first turn on the helicopter, the best thing to do is set it down on a solid place, and observe that the LED goes solid. If you keep your helicopter in your hand, and you keep moving it around, the LED will never go solid, and your controller will never be able to communicate with it.

Any suggestions on where the problem lies...

My nephew's S107G has developed a wobble...

It is obvious when it first spins up but is actually there at all times.

Here's a short video during takeoff.

Ken, I would suggest that you or your nephew check the pivot pins. If you're not sure what I'm referring to, please visit my blog for a detailed discussion. It might be the cause of that wobble.

Hi. I bought one of the new S107s, and it doesn't like to turn left very much. Is that normal? It does turn, but to even out the turning when I'm moving I have to trim waaay left. Other then that, it flies extremely well. Not as stable as the old one, but quite a bit faster.
